TELEGRAPH-TRANSMITTER.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed June 17, 1905. Serial No. 265,706.

To all whom, it inaty concern.-

Be it known that we, BENJYMAN P. HAYES and SIGEL H. GILL, citizens of the United States of America, residing at Topeka, in the county of Shawnee and State of Kansas, have invented new and useful Improvements in Telegraph-Transmitters, of which the following is a'specification.

Our invention relates to mechanical transmitters comprising a series of symbol-disks mounted on a constantly-rotating shaft with a series of keys and key-levers for controlling the symbol-disks to hold them in their normal stationary position or to release them, so they will revolve with the shaft, the rotation of the symbol-disk against a brush causing the make and break in the main line.

The objects of the present invention are to produce a simple and efficient telegraphtransmitter; to produce such a machine in which the several parts are such that they can be made at a minimum cost and yet which are durable and not easily gotten out of order; to provide a simple and efficient,

friction-clutch for controlling the symboldisk by thekey to produce a simple, efficient and practical means for operating the transmitter by the keys of a type-Writer, so as to operate the type-writer and the transmitter simultaneously, special attention being given to the particular means and mechanisms employed for this purpose and also special attention being given to the feature of quickly and readily and easily attaching our transmitter to any ordinary type-writer without any alteration of the latter machine.

Other objects will appear hereinafter.

To these ends the invention consists of the parts ,improvements, and combinations here- 1n shown and described and claimed.

In the drawings accompanying and forming part of this specification and in the description thereof we have illustrated the invention in its preferred form and have shown the best mode of applying the principles thereof; but it is to be understood that the invention itself is not confined to these drawings and the description of the drawings, that it may be applie to other uses, and that parts and -comb1nations thereof, as herein separately claimed, may be used in connection with other devices of asimilar general nature, and that we contemplate changes in form, proportion, material, arrangement, transposition of parts, and

to show the arrangement of the symboldisks,

the transmitter key-levers, and the electromagnet attachments for operating the disks by the type-writer keys. Figs. 4, 5, 6, 7, 8, 9, and 10 are details of the symbol-disk and the friction-clutch, Fig. 10 being a sectional view of these parts assembled on the drivingshaft. Fig. 11 is an alternative manner of constructing the disk. Fig. 12 is a detail in cross-section through the line 12 .12 of Fig. 15 of the type-writer attachment device. Fig. 13 is a side view of the commutator-bar. Fig. 14= is a side view, but partly in section, of the commutator-jack; and Fig. 15 is a plan view of the attachment device, showing parts of the nether portion of the type-writer frame and several of the t e-writer keys. Fig. 16 is a detail of the r al for winding the spring-motor.

Like reference-numerals indicate like or corresponding parts throughout the severa views. I

1 is the base-plate of the frame. 2 represents the corner-posts. 3 is the top plate. 4 is the front plate, which is bulged at 4 to ac commodate the brush-holder 22. 5 5 are the side plates, and 6 is the back plate.

In a bearing-bracket 7 at each end of the machine is mounted a drive-shaftS, provided ler-ratchet mechanism throughout its length with one or two keyways 9 9. On the shaft are mounted the symbol-disks 10 10 10, constructed as follows: We make two disks or plates 11 11 of suitable conducting material and divide the periphery into dots and dashes, with air-gaps between to correspond to the characters which the s bol-disk is to represent. Thedisk shown in detail in the drawings represents the period, and there are three periods on the disk, so that the disk is required to rotate but onethird of a complete circle to transmit that character. It is understood, however, that there may be more or less than three characlisk without departing from the 2 5 friction-disk to ta @nrings r BEST A I0 contact of the brushes 21 with the metal plates 11 1 1. r

We provide a disk 16 for each symboldisk. The disk 16 is of a size that will fit in the ring 13 and is provided with lugs 17 17,

15 corresponding with the keyways 9 9 of the drive-shaft, whereby the said d1sk'16 may be splined onto the drive-shaft by slipping it on at the end. The disk 16 also has the radial slots 19 19, into which are fitted the friction 2o brushes or wings or springs 18, which consist simply of a spring bent upon itself, as shown. These springs tend naturally to extend outwardly. Between the springs and the inside surface of each of the plates 11 is a washer or e up the wear of the brushes. The parts are assembled by plac ing the ring 13 onto one of the plates 11, then placing within the ringa washer 20, then the clutch 16 with brushes 18 18, then another o washer 20, and then the other plate 11, and

' securing the parts together by suitable means, as by screws 14 14. The whole symbol-disk may then be mounted on the drive-shaft by slipping the shaftthrough the central open- 3 5 ing, with lugs 17 1,7 in keyways 9 9.

The brush-holder 22 is secured to but insulated, 23, from the front plate 4 of the frame and is provided with a series of brushes 21, preferably one for each symboldisk, and

0 through the bracket 24 are the adjustingscrews 25 25, the brushes being adapted and adjusted to bear with the desired pressure against symbol disk, brushes and disks (through drive-shaft and frame) being con- 5 nected up with op osite main-line wires 28 and 27, respective y. A switch 29 is pro-. vided to cut out the machine from the main line, when desired. This switch is simply a metal-lever switch commonly used, consist- 5: ing of a metal lever or spring pivoted to one post 29 and adapted to be turned onto or off of the other post 28", which two posts are connected up with the main-line Wires by the shunt-wires 29 and 28, respectively. When 5 5 the switch is closed, the main line passes therethrough. When it is opened, the main line passes through the transmitter disks and brushes.

To a slotted fulcrum-block 31 at the rear 6.0 of the machine are pivoted a series of key-levers 32 32, provided with keys 33 33. one key-lever for each symbol-disk. The levers extend out through slots 34 in the front plate 4 and are held in normally raised position by On one side of? 2 so ,aee

lLABLE COP an auxiliary lever 37, pivoted at 36, the other end 41 working loosely in the cl eat 42, fastened to the key-lever 32. The auxiliaryis sustained in normally permanent relation with the key-lever by the spring 43 and is notched at 39, so as to engage as a stop the pin 38, extending laterally from the side of the symbol-disk. There are as many pins on each disk as there are characters. Thus in the case illustrated there are three pins and three periods, and they are so arranged that when the shaft is turning in the direction indicated by the arrow a'pin 38 will engage notch 39 and hold the symbol-disk stationary with brush 21 on an insulated portion 26, although the friction disk and springs 18 18 rotate with the drive shaft and within the larger disk. On depressing the key 33, however, the large disk will be permitted to rotate with the drive shaft and friction' brushes until the key be released, so as to engage a pin 38 with the notch 39. In ordinary sending there would be simply a light quick touch upon the key and its immediate release, which would cause the transmission of a single character; but if desired to repeat that character it is plain that this would be done by holding the key down.

on each auxiliary lever 37 is an armature 44, and under each armature is an electromagnet 45. These magnets, armatures, and auxiliary levers are preferably arranged in mismatched relation, which permits them to be compacted together in comparatively small space, the magnets being sustained on the supporting-plate 46, secured by hangers 47 47 to the base-plate 1. The wires for these magnets are connected up with the type-writer keys corresponding to the symbol disks, respectively, so that there is a separate circuit for each magnet controlled by its respective type-writer key, although it is plain that a single battery and a common return-wire may be used for all the circuits. Thus the wires 49 48 48" 48" are connected through a cable and devices hereinafter explained in detail from one side of said magnets, respectively, to the respective contactsprings 75 75, as explained hereinafter, while t e common return wire 48 connects the other side of all the electromagnets with the universal contact-strip 63, thusmaking in a well-known manner a number of independent circuits with a common return-wire and o erable by a single battery 49. Preferalily we carry these wires in a cable 50, and

we will now explain the manner of connecting with the type-writer key-levers.

A cylindrical piece of insulating material 52 is provided with a handle 51, through which the wires 53 (corresponding to the wires 48 49 48, &c.) of the cable 50 extend and on which are'mountecl alternately rings of conducting and non-conductmg material, 3 wires being con- BEST AVAlLABLE COP nected up with the metal rings, respectively. The fiber commutator 57, having the hole 58, is slotted at 59 59 to correspond with the metal rings on the jack just explained, and in each slot is a spring 60, whereby connectionis made between the wires and the springs 60 60 by simply inserting the jack in the commutator. Extending between the end brackets 61 61 I is the insulation-bar 62, on which is mounted a contact-stri 63, these parts being ada ted to be secure to the side bars 65 65 o the type-writer frame and under the key-levers 64 6 1 bymeans of the pointed set-screws 66 66 and lock-nuts 67 67. The bar 62 has grooves 71 above and below. For each keylever is a bracket 68, having a hook 69 to engage the upper groove and a set-screw 70 to engage the lower groove and hold it in place. A spring-button 72, sustained on a spring 73 and adapted to be moved up and down and removed readily, or the entire attachment may be removed or put on any ordinary 3 ter machine. .1 be not used, the auxillary levers will co6per-.

type-writer without any alteration of the lat- If the type-writer attachment ate with the key-levers 32 as if solid therewith, and if the electromagnet attachment be used the armatures and auxiliary levers 37 will be drawn down, so as to release pins 38 without moving the main transmitterlevers 32, the springs 43 serving to restore and maintain the auxiliary levers in normal position. If it be desired not to have the electromagnet attachment, the auxiliary levers may be dispensed with, the notch 39 being made in the main lever. As it is shown, however the main lever is cut away at 40 to allow the proper movement of the pins.

A universa stop-bar 82 extends along under the type-writer key-levers and is provided with a handle 81 and is adapted to be shifted to the position 83. (Shown in dotted outline.) In the first position the type-writer keys have a limited movement only sufficient to take up the lost motion without operating the type-bars, but of sufficient range to press contact-spring 75 against contact-strip 63. In the second position of the stop the entire movement of the type-writer key-lever oc curs, the additional movement being taken up in the two springs 73 and 75. In the first position only the transmitter is affected by the manipulation of In the second position both machines are operated simultaneously, while if it be desired to operate only the type-writer the transmitter may be wholly disconnected. Obviously, too, the transmitter may be operated without the type-writer by the transm1tterke s.

Any suitable motor may be provided for driving the drive-shaft 8, as an electric mo tor or a spring-motor, of any suitable construction and with suitable governing devices to drive the shaft at any suitable speed. We have illustrated one kind of motor, a springmotor, built somewhat on the order of the common curtain-shade roller and comprising a train of three of these rollers or tubes and springs with suitable roller-ratchet for winding it and suitable intermediate gearing.

A large gear 78 is attached to the driveshaft and meshes with gear 79, which is attached to the smaller gear 80, which meshes with gear 90, keyed to shaft 91, to which is secured one end of the long coil-spring 92, the other end of which is secured to the gear 93. Gear 93 meshes with gear 94, to which is secured one end of coil-spring 95, the other end of which is secured to shaft 96, to which is keyed gear 97, which meshes with gear 98, to which is fastened one end of spring 99, the other end of which is secured to shaft 100, on the other end of which is the smaller gear 101, meshing with the larger gear 102 on shaft 103. The crank 104 has a handle 105 and a number of cam-sha ed recesses 106 106 106, in which are the r0 lers 107 107 107. A detent 108 prevents the springs from unwinding exce t in turning the shaft. The motor is woun by the operation of the crank. The coil-springs may be inclosed in the tubes 77 7 7 7 7, respectively.

The washers 10 10 keep the disks properly spaced apart on the shaft.

Our arrangement of friction-clutch reduces to a minimum the amount of friction necessary in this form of device and also prevents the tendency to throw the disks out of their proper position because of the brushes bearin against opposite faces of the same disk.
